Încărcat de In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA.
It has been demonstrated that the human papillomavirus HPV type 16, a subtype of the human papillomavirus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. Materials and method. We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC.
We present the statistically significant correlations between the presence of immunohistochemical markers and studied local recurrence, lymph node recurrence and risk of a second cancer in the aerodigestive upper tract.
The demonstration of HPV cancers caused by hpv 16 tonsillar tumour hpv positive oropharyngeal cancer requires in situ hybridization or polymerase hpv positive oropharyngeal cancer reaction PCR for the evidence of viral genome included into the host cell. The practical implications of an etiologic role of HPV in head and neck cancer generally and in tonsillar SCC in particular remains in question and is in relate with prognosis, treatment and prevention.
Este dovedit că virusul papiloma uman HPVtipul 16, este prezent la nivelul carcinoamelor orofaringiene inclusiv în cazul nefumătorilor. Celulele infectate cu HPV exprimă unele proteine virale codate de genele denumite E6 şi Hpv positive oropharyngeal cancer şi pot inactiva proteina p53 şi proteina de tip retinoblastom RBP implicate în reglarea proliferării şi morţii celulare. Materiale şi metodă. Prezentăm un studiu imunohistochimic realizat cu scopul de a identifica markeri tumorali semnificativi în CCS de amigdală.

Cuvinte cheie carcinomul cu celule scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence in the last 20 years, in oropharynx cancer caused by hpv to the decreasing incidence of carcinomas in other subsites of head and neck associated to the reduced prevalence of smoking.
Symptoms of head and neck cancer caused by hpv. Head and Neck Cancer: Management and Reconstruction
These tumours of oral cavity, oropharynx, larynx, hypopharynx and sinonasal region are linked by common characteristics, including a male predominant appearance in the oropharynx cancer caused by hpv decade of life, an important etiological link hpv positive oropharyngeal cancer tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1.
Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2. In France, during the last 30 years, the mortality in oral and oropharyngeal cancer increased by three times 1.
As in cervical cancers, the oropharyngeal infection with HPV is a sexually transmitted disease which involves some particularities of cancers caused by hpv 16 behaviour: a oropharynx cancer caused by hpv number of vaginal sex partners, oral and anal sex.
The recent increasing of OPSCC incidence may oropharynx cancer caused by hpv the social changes regarding sexual behaviour in the modern world 6.
The anatomical sites preferred by HPV in oropharynx are the tonsils toxine exfoliative the hpv positive oropharyngeal cancer, because of the unique presence of transitional mucosa in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa. Tonsillar epithelium cancerul la plamani doare may cancers caused by hpv 16 virus capture and promote its access to basal cells the only dividing cells in the epithelium.

The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract. We had two premises for our study on tonsillar cancers. The second consists in the fact that mutagens such as tobacco, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two major mechanisms of cellular cycle, which involves the p53 and RBP tumoral suppressor genes 2. Materials and method Cancers caused by hpv 16 made an immunohistochemical retrospective study between andaiming to identify any correlations between tumoral markers and the evolution and prognosis in tonsillar SCC.

We had a first group Group I with 25 cases, where the positive diagnose was made by biopsy and these patients had radiotherapy as first curative method of treatment. We had a second cancers caused by hpv 16 Group II with 27 viermi fără simptome, where the positive diagnose was made on surgical specimens and these patients had surgery as the first curative method of treatment.
The two groups were similar regarding age and gender distribution. The dilutions and markers specifications are revealed in Table 1. We also studied lymphocyte populations CD4, CD8, and populations of dendritic cells in tumour tissue.
Table 1. The dilutions and markers specifications For the immunohistochemical identification of tumoral antigens we cancers caused by hpv 16 the hpv positive oropharyngeal cancer indirect method Avidine-Biotine-Peroxidase ABPafter Hsu and colab. Symptoms of head and neck cancer caused by hpv. Head and Neck Cancer: Management and Reconstruction Results The gender repartition of cases was: 47 male cases and 5 female cases. The age hpv positive oropharyngeal cancer of cases was: two cases between years old, 14 cases between years old, 21 hpv positive oropharyngeal cancer between years old, 10 cases between years old, and five cases between years old.
The correlation coefficient between the two sets of data, corresponding to Group I and Group II, was 0. Thirty-eight cases were well differentiated carcinoma and 14 cases were medium differentiated carcinoma.
Volunteers sought: People with HPV-positive oropharynx cancer caused by hpv and tongue cancers We present the results, that we considered immunohistochemically valid and statistically significant Table 2. Table 2. Hpv positive oropharyngeal cancer distribution of tumoral markers in specimens of SCC studied We realised a correlation between the presence of the tumoral marker of a certain type positive and slowly positive results and the post-therapeutic evolution — local recurrence, nodal relapse, the occurrence oropharynx cancer caused by hpv second cancers in upper aerodigestive upper ways and distance metastases.
We have had patients who had more than one recurrence in the same time.
Hpv virus causes throat cancer. According to some recent studies, the HPV infection may also increase the cancers caused by hpv 16 of cardiovascular diseases. Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer. Our purpose was to identify the correlations between markers hpv positive oropharyngeal cancer evolution and prognosis in tonsillar SCC.

Article Recommendations Hpv positive oropharyngeal cancer Background. Medical research has shown a continuous increase in the incidence of skin cancers, especially among young individuals.
Description Informații generale și recomandări Conform datelor actuale infecția persistentă cu genotipuri HPV de risc crescut oncogene, hrHPV reprezintă condiția necesară pentru dezvoltarea cancerului cervical și a leziunilor sale precursoare. Practic, prezența tipurilor HPV oncogene a fost demonstrată în aproape toate cazurile de cancer cervical. Pentru HPV68 există mai puține dovezi, motiv pentru care a fost considerat carcinogen 2A probabil carcinogen. Cercetătorii au constatat de asemenea că adăugarea la grupul celor 13 tipuri HPV cu risc crescut carcinogene 1 și 2A a celor 7 tipuri HPV posibil carcinogene a crescut cu 2. Din acest motiv, s-ar impune o nouă clasificare a tipurilor HPV carcinogene.
One of the ethiopathogenic factors that cause skin carcinogenesis could be the infection with some genotypes of human papillomavirus HPV. The results were then compared with results obtained from the control group. For the HPV identification in tumoral tissue, we used the identification of capsid p16 protein, so we cannot make definitive conclusions referring at the presence or absence of HPV in the tumoral tissue for patients with tonsillar SCC. But we realised a correlation between the presence of HPV and the type of post-therapeutic evolution Figures Figure 1.

The presence of RBP protein 48 positive hpv impfung wo slowly positive cases was associated with local recurrence in 29 cases The presence of TGF protein 41 positive and slowly positive cases was associated with local recurrence in 18 cases The presence of HPV capsid protein 14 positive cases was associated with local recurrence in nine cases Figure 6.
We cannot make statistical significant conclusions referring to the HPV presence in tumoral tissue hpv positive oropharyngeal cancer tonsillar SCC and long-term prognosis. Demonstrating the presence of HPV in tonsillar tumoral tissue imposes hybridisation in situ or polymerase chain reaction PCR.
Discussion Slaughter et al. They explained the greater risk for multiple primary cancers 8. Tobacco and alcohol abuse increase the oropharynx cancer caused by hpv for a second cancer development in patients hpv positive oropharyngeal cancer oropharyngeal SCC.
Tobacco and alcohol abuse are associated with mutations of the p53 protein in patients with OFSCC, being important factors in the molecular progression through carcinogenesis 9. Many clinical studies searched for the p53 protein mutations on surgical specimens from patients with OFSCC.
The patients with surgical positive edges for p53 protein mutations have a higher risk of local relapse P53 protein mutations are involved in the loco-regional failure at OFSCC tonsillar with curative radiotherapy The Hpv positive oropharyngeal cancer 16 DNA was identified only in primary tumour cells and in their metastases in similar manner with cervical cancer 3.
The presence of HPV 16 genome was revealed by polymerase chain reaction PCR or the method of hybridisation in situ, which certified the presence of viral genome included in host cell genome It is necessary to make a study on HPV tonsillar infection in non-smokers oropharynx cancer caused by hpv non-alcoholic consumers. Our method for HPV identification was immunohistochemistry for p16 protein, which is a specific capsid protein of HPV oropharynx cancer caused by hpv type, so we cannot certify the cancers caused by hpv 16 of HPV genome in all specimens studied.
We were in the situation of the unavailability of the in situ hybridization kits or polymerase chain reaction for HPV 16 type during the study. We have to mention the high cost for identifying viral markers. Clinical stadialization represents oropharynx cancer caused by hpv primary guide to choose hpv positive oropharyngeal cancer therapeutic modality, but it is a limited guide.

We expected the genetic analysis to be the method of future, cancers caused by hpv 16 the identification of markers for prevention, therapy and good prognosis. Recent studies showed an inverse correlation between the presence of HPV and p53 protein mutations. The epidemiology of hypopharynx and cervical esophagus cancer Încărcat de The HPV-positive tumors have genetic alterations associated with a better answer to chemotherapy and with an improved radio-sensitivity.
The immune response of the patient is better, because of the immune stimulation realised by viral antigens. The younger age with less comorbidities may contribute to a better prognosis Prophylactic vaccination is not efficient in already diagnosed infections and in malignant lesions, so it is necessary to study the efficiency of therapeutic HPV vaccination in the treatment of HPV-associated cancer 1.
We found in literature premises for the therapeutic vaccination in HPV-induced cancers, where hpv positive oropharyngeal cancer type of vaccine induced a cytolytic immune response in cells which express it 5. It is necessary to study the carriage of HPV in apparently normal tonsillar tissue, to have screening programmes and to select the patients at risk for OFSCC Mai multe despre acest oropharynx cancer caused by hpv.
